anybodys lo losing a lot of hair?

My son had a lot of hair first 4mo. Now this past week it seems to be shedding.
I run my fingers through his hair and i get a few strands of it on my hand.
When i wash it and its coming off.
I look on his sheets and its on there as well.
I know babies lose hair but i thought it was later on like 7-8 months.
Is this normal?

Sounds pretty normal my LO has lost a lot esp round the back poor little thing has a hair style like kim jong un at the mo my first LO lost her jet back hair and is now a blonde not sure if this LO will have light hair or not yet
